RE: SYSSA 30CC GAS MADE IN USA
I just got back from flying mine with the new drive plate with the 2 shear pins. For the last flight, I made a Syssa advertisement in front of the other guys. All I did was work the throttle a couple of times (got to love the accelerator pump carb) on a cold engine and it started with 1 flip! It was fairly windy, but it was right down the field, so landing this EF Extra is easier than a trainer, and my harriers are getting halfway decent. Hovering is a blast and the pullout with the Syssa on the ES pipe is like an Estes rocket, and I am still using a Vess 18-6. Good day for this newbie, and I might have some flying videos as well.

He was talking about rpm X prop pitch does not add up to 104

Using the rpm x prop pitch calculations gives me a max speed of 55 mph with a 6" pitch at 9600 rpm. I get 9000 rpm on the ground. That seems about right for my Sportster, I think it is in the 40 to 45 mph range most of the time. I get more noise at WOT, but very little speed increase, maybe 5 mph. Unloading does not do much for the speed on my plane. There is no way I ever keep up with a Stick, they go past me like I'm standing still. I might be able to get 70 to 75 mph with a 10" pitch prop. My CL combat special was running in the 15K to 20K range on the ground with an 8" prop.
We will need to get the old radar gun out and make some measurements.

good to hear I am waiting for my Syssa to return to me after repairs. (shear-pin let go) I have mine on a Slipstream sbach and it is a perfect match!! I am not using a spinner though I am hopeing for a little input as to which one. Good fun!!

Could be right. To get 100 mph, you need to turn a 10'' prop at least 10,560 rpm.
Using the rpm x prop pitch calculations gives me a max speed of 55 mph with a 6'' pitch at 9600 rpm. I get 9000 rpm on the ground. That seems about right for my Sportster, I think it is in the 40 to 45 mph range most of the time. I get more noise at WOT, but very little speed increase, maybe 5 mph.

I had a hot rod S10 at one time with a engine and transmission for different vehicles
I timed myself with the mile markers on the highway in front of the house. I selected different speedometer gears from other transmissions I had until I got the speedometer right on.

I once rode a pony so I could more accurately determine horsepower.....

Just an interesting note, if the gun was set on kph a readout of 104 would be 64.6mph. Easy way to check would be to hop in a car with someone and point it at a road sign.

I was going to suggest that you drive a car down the flying field at 100 mph to see if the plane can pass it, but I guess checking the gun against a road sign would work too.

RE: SYSSA 30CC GAS MADE IN USA
That was my next thought, straight down the centerline in my Vette. See if my uglystik could catch her...
I wasn't holding the radar but was assured it was set to MPH.
It flys pleanty fast enough for me at whatever MPH, let's put it to rest.
Has anyone determined if the "latest" version of the SAP180 comes with the new style hub?

RE: SYSSA 30CC GAS MADE IN USA
Had the key shear on my engine and Todd replaced with new key,new keys are nickle plated so he can tell new from old and replaced hub with new alum. hub,nice contrast to black of engine.New hubs are maybe 1/32 inch longer than old hub and have holes for roll pins to hold spinner back plates + two threaded holes.He also gave me a drilling jig,drill,pins and adapter to hold backplate or prop while drilling.Super service from a great guy.Rich

No engine yet, I emailed Todd for status and was promised it next Tues/Wed. Apparantly, a tracking number is beyond the scope of the ''Syssa shipping department''.
Not that it matters much, I'm in Iraq until early next year. I have a new 74'' ESM corsair ordered and received within 1 week from VQwarbirds. I also got the sierra retracts and cockpit kit. The syssa should fit nicely in the cowl.
My current Sap 180 pulls my 80'' giant stick vertical and has clocked 104mph on stock exhaust and 18x6 mejzlik. It should have no trouble pulling the corsair.
Anyone else flown ESM warbirds with Syssa?

RE: SYSSA 30CC GAS MADE IN USA
So I suppose the consensus is that this is a good engine, right? Will it pull a scale model in the 20-25 pound range? Model is a Ryan ST-A, from Byron Originals.

RE: SYSSA 30CC GAS MADE IN USA
I think it will fly it, but @ 25 lbs it will be marginal on power and might also require additional
weigt in the nose to achieve CG. The SAP is a very lightweight gasser!

Someone should have an engine with a new style hub by now. Even if they were shipped by pony express, travel between the Atlantic and Pacific coasts only took about ten days, of course the ponies are getting pretty old by now so I would expect them to be a little slower, I know I am.

Yep,
Just got the email from the wife; a package from Syssa arrived yesterday, Aug 17. one month is better than two. Thanks for the intel on the new hub. I look forward to seeing it in Feb.
I think the Syssa will pull that Stuka around no prob,I'd like to see some pics. I'd re think the 25 pounder unless it's with a pipe.

RE: SYSSA 30CC GAS MADE IN USA
The resolution is not the greatest but at least you can hear the Syssa/ES pipe combo. It was really cloudy and windy, but I was having alot of fun, 22 pounds of thrust on a 11.8 pound plane does move well indeed!

If you send the engine to me, I'll find something to put in on and have it broken in for you when you get back. I hate the thought of it just laying around collecting dust when it could be up the the air fulfilling it's destiny.

I bet you will! That's very kind of you to offer but I think I'll keep her safely stored until us "Non Combat" troops come home from Iraq.

Can anyone tell me what is the designed regulated voltage to a CDI system from a SAP Ultra IBE unit. Thanks.

Karol
The ultra IBEC output voltage is adjustable, I believe. There should be instructions as to what one can do to tailor voltage output. I don't have Ultras so I am not certain of that, but if I remember right, the output is maxed out at 6 volts. Todd should have the instructions on his website
